0.70 Ct. Cabochon Chrysoberyl from Ceylon (Sri Lanka)

One beautiful translucent 0.70 carat round yellowish green chrysoberyl is offered by The Natural Gemstone Company, originating from Ceylon Sri Lanka. The gem measures 4.87 by 4.78 by 2.88 millimeters, and it has been fashioned into a classic round cabochon with a gentle, well balanced dome. The cabochon cut was executed to preserve translucency while maximizing the visual presence of color, and the piece displays a medium color intensity that reads as a fresh yellowish green under standard daylight viewing conditions. The clarity is graded as eye clean at eye level, with internal silk like inclusions arranged in such a way that they do not interfere with naked eye observation of the stone, and there are no indications of filling, dye, heating, or other enhancements. The polish is excellent, resulting in a smooth, reflective surface that supports sharp light reflection and a clean chatoyant band when illuminated by a directed light source.

From a lapidary perspective the cabochon demonstrates deliberate choices in thickness, dome curvature, and orientation relative to the directional inclusions. The dome height is proportioned to the dimensions of the piece, providing sufficient depth to reveal internal structure while keeping the profile wearable for a variety of settings. The cutter centered the banding to produce a single, well defined chatoyant stripe across the crown, a result of fine, parallel oriented silk within the chrysoberyl that has been aligned during shaping. The absence of facet junctions focuses attention on surface finish, and the excellent polish minimizes surface haze, allowing the intrinsic translucency and the chatoyancy mechanism to operate with clarity. Technically minded buyers will note that chrysoberyl in general is a high hardness species, registering about eight and a half on the Mohs scale, and that its refractive index falls in the approximate range 1.743 to 1.755, with a specific gravity near 3.73, properties that contribute to its durability and resistance to wear when set in jewelry that receives regular use.

Optical behavior and setting recommendations are important for realizing the best aesthetic outcome. The chatoyant band is most pronounced when the cabochon is cut with the silk inclusions parallel to the base, and when the stone is oriented perpendicular to the light source, producing a sharp eye that travels across the dome as the piece is rotated. For mounting consideration a bezel or partial bezel setting will both protect the girdle and maintain the controlled light path needed to display the cat eye effect, while open backed settings can be used where increased light transmission is desired without compromising the cabochon profile. The medium color intensity makes the piece versatile for metals ranging from yellow gold to white gold and platinum, with yellow gold tending to warm the hue slightly and white metals preserving the crisp green leaning tone. The combination of eye clean clarity at normal viewing distance, excellent polish, and natural, unenhanced origin from Ceylon Sri Lanka makes this specimen suitable for collectors who prioritize natural provenance and for jewelers who require a stable, durable stone for everyday wear.

The Natural Gemstone Company certifies that this chrysoberyl is natural, untreated, and free of enhancements, and we provide detailed documentation on request to support provenance and gemological characteristics. For buyers seeking customization we can advise on orientation, mounting profile, and companion accent stones that will complement the yellowish green tone without overpowering the chatoyant feature. Care recommendations include avoiding ultrasonic cleaners in the presence of inclusions that may contain fluid filled features, cleaning with warm soapy water and a soft brush, and storing separately to prevent surface abrasion. This 0.70 carat round cabochon chrysoberyl from Ceylon Sri Lanka presents a technically refined example of cabochon cutting and natural optical phenomena, an appealing choice for those who value precise craftsmanship and documented natural origin.
